To confirm this, the research team led by Alison Wood Brooks did a series of experiments; go here for the whole summary. Let's focus on one revealing experiment. From Time:

[R]esearchers paired participants with an unseen partner that they could only communicate with over instant message.

The participants were then asked to do a brain teaser, before handing the task off to their partner. Once they'd finished the task, they received a message from their "partner" that either read, "I hope it went well. Do you have any advice?" or "I hope it went well." Later, when asked by the researchers, people rated the partners who asked for advice as being more competent than those who had simply wished them well. What's more, the harder the brain teaser, the more competent the advice-seeking "partners" were rated.

The carryover to office life: When you encounter a particularly woolly problem, don't hesitate to grab someone who has dealt with similar cases. There is a good chance they will actually think more of you afterward. “Not only is advice seeking beneficial for the spread of information, but it may also boost perceptions of competence for advice seekers and make advisors feel affirmed,” Brooks and her colleagues write. “By failing to seek advice, individuals and their organizations miss opportunities to share knowledge and improve interpersonal outcomes.”
